It was outside

I was looking outside, through a window, when I spotted a fly.

It went round and round, up and down... my little catty eyes really had to focus to keep track of it.

Suddenly, I found it annoying and got the urge to bite it.

I forgot that I was indoors.

I went to bite it and hit my head on the door.

This really confused me and made me do catty head shakes.

I lost sight of the fly.

I wasn't happy, so I went to eat some catty biscuits.
